Cal. Family Code § 8820

(a) The birth parent or parents or the petitioner may appeal in either of the following cases: (1) If for a period of 180 days from the date of paying 50 percent of the fee, or upon the expiration of any extension of the period granted by the court, the department or delegated county adoption agency fails or refuses to accept the consent of the birth parent or parents to the adoption. (2) In a case where the consent of the department or delegated county adoption agency is required by this chapter, if the department or agency fails or refuses to file or give its consent to the adoption after full payment has been received. (b) The appeal shall be filed in the court in which the adoption petition is filed. The court clerk shall immediately notify the department or delegated county adoption agency of the appeal and the department or agency shall, within 10 days, file a report of its findings and the reasons for its failure or refusal to consent to the adoption or to accept the consent of the birth parent or parents. (c) After the filing of the report by the department or delegated county adoption agency, the court may, if it deems that the welfare of the child will be promoted by that adoption, allow the signing of the consent by the birth parent or parents in open court or, if the appeal is from the refusal of the department or delegated county adoption agency to consent thereto, grant the petition without the consent. (d) This section shall become operative on October 1, 2008.
